PARIS, July 18 (Reuters) - The man who killed 84 people in Nice had planned his attack in the days prior to Bastille Day and had recently developed an interest in radical Islam, the Paris prosecutor said on Monday.

"If there are no elements in the investigation to suggest at this stage an allegiance to Islamic State nor links with individuals from the group ... he (Mohamed Lahouaiej Bouhlel) showed a certain recent interest for radical jihadist movements," Francois Molins said.
